Abstract

Male pigs n = 6 and a LigaSure V device and an Atlas 20 Valleylab Boulder CO USA device were used in this study After laparotomy the common bile duct and the right and left firstdegree Glisson bundles were sealed by the VSS The lower and upper parts of the common bile ducts were also sealed Macroand microscopic examinations were performed for the analysis of specimens taken just after VSS application In an analysis of bile duct specimens taken 1 week after the VSS application both burst pressure tests and histological examinations were performed1 In the analysis of the specimens Glisson bundles and bile ducts obtained just after the VSS application the macroscopic changes included permanent flattened changes of the Glisson bundles and bile ducts without showing any blood or bile leakage Histological examination of the transverse sections of the Glisson bundle after VSS application revealed that not only the blood vessels but also the bile ducts were fused together 2 In the analysis of the specimens bile ducts obtained 1 week after the VSS application secondlook laparotomy showed extrahepatic bile duct obstruction The mean burst pressure of the sealed bile ducts was 744 ± 201 mmHg Histological examination revealed that the lumen of the bile duct was completely sealed and the duct was surrounded by dense connective tissues
